Wiley J. Youngs and Claire A. Tessier, Department of Chemistry, University of Akron, are supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program for the synthesis and study of heterocyclynes. These cyclic polyalkynes contain silicon, germanium, platinum, titanium and other heteroatoms that will tune the size and chemistry of a binding pocket. The project will also extend heterocyclynes to complexes containing metal-metal bonds, dipocket heterocyclynes that contain a Lewis acidic site and a Lewis basic site, heterocyclynes that have larger pockets or can act as molecular tweezers, and heterocyclynes that have unique materials properties such as liquid crystallinity, semiconductivity or non-linear optical activity. Heterocyclynes are a key building block in supramolecular chemistry. These analogs of tribenzocyclotriyne have well-defined pockets that can selectively bind metal ions and other guest species. They are also potential components of molecular electronics. Students trained in this area will develop skill in synthesis, spectroscopy and crystallography.

阿克伦大学化学系的 Wiley J. Youngs 和 Claire A. Tessier 得到了无机、生物无机和有机金属化学项目的支持，用于杂环炔的合成和研究。这些环状聚炔含有硅、锗、铂、钛和其他杂原子，可以调节结合袋的尺寸和化学性质。该项目还将杂环炔扩展到含有金属-金属键的配合物、含有路易斯酸性位点和路易斯碱性位点的双口袋杂环炔、具有较大口袋或可以充当分子镊子的杂环炔，以及具有独特材料特性（例如液晶性、半导电性或非线性光学活性）的杂环炔。杂环炔是超分子化学的关键组成部分。三苯并环三炔的这些类似物具有明确的口袋，可以选择性地结合金属离子和其他客体物质。它们也是分子电子学的潜在组成部分。在该领域接受培训的学生将培养合成、光谱学和晶体学方面的技能。
